Heather Langenkamp is a welcome presence in "A Nightmare on Elm Street 3: Dream Warriors," reprising her role from the classic original as survivor Nancy Thompson. Now a psychologist specializing in dream therapy, she has been hired by psychiatric hospital Westin Hills to work with a group of teens who are experiencing traumatic nightmares. When new inmate Kristen (Patricia Arquette in her big-screen debut) pulls Nancy into one of her dreams, it becomes clear that Freddy Krueger has returned to claim the last of the Elm Street children. "A Nightmare on Elm Street 3: Dream Warriors" features vivid dream imageryall of the films in the series dobut the burn-faced night stalker simply doesn't make the impression here as he did in the former two installments. The ending, which claims a victim that should have never become one, and also features some silly business with the skeletal remains of Freddy hidden in a junkyard, is disappointing. Heather Langenkamp, dressed in unflattering suits and with an overly permed head of hair, is made to look more like Langenkamp's mother than the twentysomething she's playing.
